Abstract
The utility model discloses a prefabricated jointing in length and breadth antiknock cement board comprising a prefabricated cement board body having several hollow conduit holes, a cross direction screw-thread steel having very strong inherent stress is laid in the prefabricated cement board body, the characteristic of the utility model is that a lengthwise direction screw-thread steel having very strong inherent stress is laid in the prefabricated cement board body, the lengthwise direction screw-thread steel lays vertically to the cross direction screw-thread steel, and the two head of both the lengthwise direction screw-thread steel and the cross direction screw-thread steel are bare out of the prefabricated cement board body to use as the soldered joint in length and breadth. The shape of the prefabricated cement board body is the narrow-end-up leanin to inside strip four arris board. This utility model has the advantages of strong anti-seismic ability and inherent stress, light weight, good effect of soundproof, being water-tight, low cost, easy to install. It is a new construction material which is suitable for building room in rural and city.
Description
Technical field
The utility model relates to constructional materials, especially relates to a kind of prefabricated cement board of antidetonation that can weld in length and breadth.
Background technology
In builing industry, cement pre-fabricated panel is owing to be provided with a plurality of hollow pipelines hole, thereby has an advantage in light weight, that sound insulation good, cost is low, quick and easy for installation, once used a very long time in China town and country, particularly the reinforcing bar in the middle of it is stretching, and added prestressing force, so intensity is also big.But because this prefabricated cement board is strip, placed side by side on load bearing wall, and do not link to each other mutually, form integral body, when earthquake takes place, if load bearing wall occurs tilting or cracking will " be fought separately ", can not form the strength of whole antidetonation, easily landing is got off from the load bearing wall, pounds on the person, causes great casualties.And between the prefabricated cement board of An Zhuaning the crack is arranged side by side, it is following to leak from above easily, and therefore prefabricated in recent years cement board is in superseded state.Though and cast-in-place plate at present commonly used have can with the interconnected advantage that becomes whole, can not leak of house beam, it must on-the-spot laying, construction speed is slow, and the reinforcing bar of interior shop is difficult to high-strength prestressing force, so bulk strength is not high; Moreover template also will be laid during construction in no hollow pipeline hole in the middle of the cast-in-place floor, therefore also has high material consumption, construction cost height, poor, the slow shortcoming of constructing of soundproof effect.
Summary of the invention
The purpose of this utility model be to provide a kind of have more strength prestressed, shock resistance is strong, in light weight, sound insulation good, water-tight, cost is low, quick and easy for installation can weld the prefabricated cement board of antidetonation in length and breadth.
The purpose of this utility model is achieved in that the utility model comprises the cement pre-fabricated panel body that is provided with a plurality of hollow pipelines hole, in the cement pre-fabricated panel body, be equipped with extremely strong prestressed horizontal thread reinforcing bar, feature is also to be equipped with extremely strong prestressed longitudinal screw reinforcing bar in the cement pre-fabricated panel body, the longitudinal screw reinforcing bar is placed with the horizontal thread reinforcing bar is vertical, and the two ends of the two ends of longitudinal screw reinforcing bar and horizontal thread reinforcing bar all are exposed to cement pre-fabricated panel, and this is external, as the vertical and horizontal welding point.
The truncated rectangular pyramids shape that is shaped as up-small and down-big strip of cement pre-fabricated panel body.
The utility model is owing to set up the longitudinal screw reinforcing bar on the basis of common precast plate, and be provided with and be exposed to this external vertical and horizontal welding point of cement pre-fabricated panel, and the truncated rectangular pyramids shape that is shaped as up-small and down-big strip of cement pre-fabricated panel body, therefore be placed on the load bearing wall the polylith cement pre-fabricated panel is adjacent side by side earlier when constructing, vertical and horizontal welding point with adjacent cement pre-fabricated panel welds together with electric welding then, the cement pre-fabricated panel on both sides then respectively with Main Girder Welding together, thereby all cement pre-fabricated panels and girder are interconnected becomes an integral body, even load bearing wall occurs or cracking can one one fall yet, pound to human body, but it is implicative of each other, be the integral inclination shape, thereby can avoid causing personnel's heavy casualties, and alleviate earthquake harm, have stronger shock resistance; And, being shaped as between the adjacent cement pre-fabricated panel " V " font groove, during construction after vertical and horizontal welding point welding finishes, with cement mortar " V " font groove is filled and led up again, the vertical and horizontal welding point is embedded in the cement mortar, it is more firm that adjacent cement pre-fabricated panel is connected, and do not have the problem of leaking naturally.Therefore the utlity model has shock resistance strong, advantage more strength prestressed, in light weight, that sound insulation is good, water-tight, cost is low, quick and easy for installation is arranged, be a kind of New Building Materials, be suitable in vast rural area and urban house-building, using.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
The utility model comprises the cement pre-fabricated panel body 1 that is provided with a plurality of hollow pipelines hole 5, in cement pre-fabricated panel body 1, be equipped with extremely strong prestressed horizontal thread reinforcing bar 2, in cement pre-fabricated panel body 1, also be equipped with extremely strong prestressed longitudinal screw reinforcing bar 3, longitudinal screw reinforcing bar 3 and the 2 vertical placements of horizontal thread reinforcing bar, and the two ends of longitudinal screw reinforcing bar 3 are exposed to outside the cement pre-fabricated panel body 1, as vertical welding point 4, the two ends of horizontal thread reinforcing bar 2 are exposed to outside the cement pre-fabricated panel body 1, as transverse weld joint 6.
Being shaped as of cement pre-fabricated panel body 1 is up-small and down-big, the truncated rectangular pyramids shape of slightly inward inclined strip.
